xmlhttprequest file upload aus string

[molily]

var form_data = new FormData();
form_data.append('myblob_filename', myblob);
xhr.params = form_data;
// und dann den POST Request

  
xhr.params? Was soll das sein? Mir nicht bekannt.  
  
Das FormData-Objekt übergibt man einfach an die send-Methode.  
  
`xhr.send(form_data);`{:.language-javascript}
